    • Aridity and overgrazing have convergent effects on ecosystem structure and functioning in Patagonian rangelands 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Aguiar, Martín Roberto; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia; Garcia Martinez, Guillermo Carlos; Maestre, Fernando Tomás (2018-02)
      Over 65% of drylands are used for grazing of managed livestock. Understanding what drives grazing effects on the structure and functioning of rangelands is critical for achieving their sustainability. We studied a network ...

    • Biotic and Abiotic Drivers of Topsoil Organic Carbon Concentration in Drylands Have Similar Effects at Regional and Global Scales 

      Gaitan, Juan Jose; Maestre, Fernando Tomás; Bran, Donaldo Eduardo; Buono, Gustavo Gabriel; Dougill, Andrew J.; Garcia Martinez, Guillermo Carlos; Ferrante, Daniela; Guuroh, Reginald Tang; Linstadter, Anja; Massara Paletto, Virginia; Thomas, Andrew David; Oliva, Gabriel Esteban (Springer, 2019-11)
      Drylands contain 25% of the world’s soil organic carbon (SOC), which is controlled by many factors, both abiotic and biotic. Thus, understanding how these factors control SOC concentration can help to design more sustainable ...

    • Climate mediates the biodiversity–ecosystem stability relationship globally 

      García Palacios, Pablo; Gross, Nicolás; Gaitan, Juan Jose; Maestre, Fernando Tomás (2018-08)
      The insurance hypothesis, stating that biodiversity can increase ecosystem stability, has received wide research and political attention. Recent experiments suggest that climate change can impact how plant diversity ...

    • Evaluating the performance of multiple remote sensing indices to predict the spatial variability of ecosystem structure and functioning in Patagonian steppes 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Ciari, Georgina; Nakamatsu, Viviana Beatriz; Salomone, Jorge Manuel; Ferrante, Daniela; Buono, Gustavo Gabriel; Massara Paletto, Virginia; Humano, Gervasio; Celdran, Diego Javier; Opazo, Walter Javier; Maestre, Fernando Tomás (2013-11)
      Assessing the spatial variability of ecosystem structure and functioning is an important step towards developing monitoring systems to detect changes in ecosystem attributes that could be linked to desertification processes ...

    • Plant species richness and shrub cover attenuate drought effects on ecosystem functioning across Patagonian rangelands 

      Gaitan, Juan Jose; Bran, Donaldo Eduardo; Oliva, Gabriel Esteban; Maestre, Fernando Tomás; Aguiar, Martín Roberto; Jobbagy Gampel, Esteban Gabriel; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia (2014-10-22)
      Drought is an increasingly common phenomenon in drylands as a consequence of climate change. We used 311 sites across a broad range of environmental conditions in Patagonian rangelands to evaluate how drought severity and ...

    • Soil fungal abundance and plant functional traits drive fertile island formation in global drylands 

      Ochoa-Hueso, Raúl; Eldridge, David J.; Delgado-Baquerizo, Manuel; Soliveres, Santiago; Bowker, Matthew A.; Gross, Nicolás; Le Bagousse-Pinguet, Yoann; Quero, José L.; García-Gómez, Miguel; Valencia, Enrique; Arredondo, Tulio; Beinticinco, Laura; Bran, Donaldo Eduardo; Cea, Alex; Coaguila, Daniel; Dougill, Andrew J.; Espinosa, Carlos I.; Gaitan, Juan Jose; Guuroh, Reginald T.; Guzmán, Elizabeth; Gutiérrez, Julio R.; Hernández, Rosa M.; Huber-Sannwald, Elisabeth; Jeffries, Thomas; Linstädter, Anja; Mau, Rebecca L.; Monerris, Jorge; Prina, Anibal; Pucheta, Eduardo; Stavi, Ilan; Thomas, Andrew; Zaady, Eli; Singh, Brajesh K.; Maestre, Fernando Tomás (2018)
      Dryland vegetation is characterized by discrete plant patches that accumulate and capture soil resources under their canopies. These “fertile islands” are major drivers of dryland ecosystem structure and functioning, yet ...

    • The MARAS dataset, vegetation and soil characteristics of dryland rangelands across Patagonia 

      Oliva, Gabriel Esteban; Dos Santos, Eder; Osiris, Sofia; Umaña, Fernando; Massara Paletto, Virginia; Garcia Martinez, Guillermo Carlos; Caruso, Cecilia Alejandra; Cariac, German; Echevarria, Daniela Carola; Fantozzi, Anabella Giselle; Butti, Lucas Ramiro; Bran, Donaldo Eduardo; Gaitan, Juan Jose; Ferrante, Daniela; Paredes, Paula Natalia; Dominguez, Erwin; Maestre, Fernando Tomás (Nature Research, 2020)
      We present the MARAS (Environmental Monitoring of Arid and Semiarid Regions) dataset, which stores vegetation and soil data of 426 rangeland monitoring plots installed throughout Patagonia, a 624.500 km2 area of southern ...

    • Vegetation structure is as important as climate for explaining ecosystem function across Patagonian rangelands 

      Gaitan, Juan Jose; Oliva, Gabriel Esteban; Bran, Donaldo Eduardo; Maestre, Fernando Tomás; Aguiar, Martín Roberto; Jobbagy Gampel, Esteban Gabriel; Buono, Gustavo Gabriel; Ferrante, Daniela; Nakamatsu, Viviana Beatriz; Ciari, Georgina; Salomone, Jorge Manuel; Massara Paletto, Virginia (2014-11)
      1. Drylands cover about 41% of Earth’s land surface, and 65% of their area supports domestic livestock that depends on the above-ground net primary productivity (ANPP) of natural vegetation. Thus, understanding how biotic ...
